Abstract

This invention relates to plant and method to obtain iron melts, in particular melt of steel, like melt of crude steel. The plant to obtain iron melt, in particular steel melt, like melt of crude steel includes an electric-arc furnace vessel, shaft for preliminary heating for supplying solid iron carriers, means for oxygen supply, refining vessel, slag discharge, weir and rotary electrodes, at that the refining vessel is placed after the furnace vessel, this has pouring weir connected to it, it goes to the bottom of the refining vessel due to, minimum, partial inclination down where the vessel named has oxygen supply means, and branch for ferrous alloy discharge placed near its end separated from the furnace vessel. The plant additionally includes decanting vessel placed after the furnace vessel and having common bottom with it, where the decanting vessel has discharge for slag placed near its end separated from the furnace vessel, means for supply of liquid pig-iron, this is opened to the furnace vessel where the shaft for pre-heating placed over the furnace vessel, intended for supply of solid iron carriers, is connected to the furnace vessel through its lid by means of gas-permeable insulating cooled unit, it includes loading shaft placed over the furnace, this is connected to the furnace vessel by means of gas-impermeable insulating cooled unit.
